I'm embarred to buy a vibrator?

My old one broke and I really want a new one and I know this shop that sells tons of toys but I'm so embarred to buy one haha! Also, I'm only 17 so I'm afraid they'll judge me even though where I am it's legal to buy one when you're older than 15.. My friends who I am comfortable enough with to go into a shop with are all away so I can't go with any of them and I really want one now. Should I be embarred? How can I feel less embarred? Also, I only want like a small cheap one, no complicated high tech machine haha, will they judge me if I buy the cheapest one they have? :P It's kind of an expensive shop but they do have some cheap stuff. Ugh this is so awkward!! haha .. thanks x
